Application filed September 14, 1887. Serial No. 249,724. (No model.)

To aZZ whom it may concern.-

Be it known that I, JAMES S. PHILPOTT, of Vindsor, county of Sonoma, and State of Galii'ornia, have invented an Improvement in Windmills; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to the class of windmills; and my invention consists in the novel details of construction and arrangement hereinafter fully described and claimed.

Referring to the accompanying drawing, the figure is a perspective view of my windmill.

A is the windmill-tower, having a standard, a, to which is secured the journal socket-s or bearings a, in which the stem hot the turntable B is mounted and pivoted. The turntable B is a single casting made, as shown, with a hollow stem, Z), a body portion, and a top portion, 25, at right angles and in boxes, on which the shaft 0 of the windwheel D is iourualed. The wheel D consists of a hub plate or flange, (Z, to which are bolted at d the blade-arms d which are preferably triangulariu crosssection and extend outwardly along the blades (2 to the connecting-braces (7. near the outer ends of said blades, and said arms are bolted to the braces and through the blades. They are also bolted to the blades at a point nearer the hubflange, as shown at (1 On the inner end of the wheel-shaft O is a crank-disk, E, which is provided with a diametrically-located dovetailedgroove, in which is fitted and adapted to slide a dovetailed bar, 6, which is provided with a wrist-pin, e, to which is fitted the boxing f of the pitman F of the pump. It will be seen that by the movement of the bar 0 the throw of the crank may be varied as desired.

G is the vane, which has a stem or shank, g, the inner end of which is pivoted by a bolt, to the head it of a pintle or hinged pin, H, which is fitted in socket-bearings b upon the top of the stem 2) of the turn-table B. The vane can move on its bolt 5 as a center through an arc in a vertical plane, and can move with the pintle H as a center through an arc in a horizontal plane, and the connection at g is such as to steady and keep the vane G from turning sidewise, being adapted to hold it straight in whatever posilion it may assume. I

In order to keep the pin II from having a tendency to rise from its socket-bearings b when the vane moves upwardly, I have formed on the head it an inwardly and downwardly curved hook it, which passes over the rim of the upper bearing 1) and engages it underneath. In said rim, however, at a point near where it joins the main body of the stem 1), is made a groove, b in which the hook h is adapted to fit when the vane is being adjusted in the firstinstance, so thatthc end of said hook may reach its proper position under the rim of the bearing and remain so when the vane is in operation, it then traveling under the rim and not in proximity to the groove 1)".

Extending outwardly from the top of the turn-table B is an arm, I, the end of which is outside of the vertical plane of the pintle II, which is the pivotal center of the vane, and to this arm is connected a hook, J, through the other end of which passes the end of the link K, said end receiving nuts k on each side of the hook J, so that by setting up the nuts the link K may be tightened to return the vane to position in case it sags. The other end of the link K is attached by a loose hinged joint at It to the vane G atits center. The effect of this construction, it will be seen, is that when the vane is forced around by the wind in order to throw the wheel into the wind it not only turns on its pivotal center at H, but by reason of it-s link-connection K it rises at the same time on its pivotal bolt 9', and returns from this position by its own gravity. In this movement, as before stated, it keeps perfectly straight, the connection at 9 providing for the proper support and the attachment of the link K to the middle of the vane effecting its operation withoutundue strain.

The vane G is also connected, as usual, with the turn-table by means of the chain L, which is attached to the shank of the vane and to an outwardly-extending arm, iiI, secured to the turn-table.

In order to throw the mill out of the wind, I have the following mechanism: Attached to the shank g of the vane is a cord, N, which passes around a guide-pulley, a, in the arm M, and thence to a guide-pulley, n, on the turn-table, and thence downwardly through the central stem of said turn-table.

The general operation of the mill is similar 5 to that of mills of this class, the invention herein lying in the improved construction and arrangement of the parts.

Having thus described my invention, what I claim as new, and desire to secure by Letters IO Patent, is

An improved windmill comprising the combination of a turntable and a vane for regulating the mill, the vertical pintle H, having a head, 71, with downturned hook h, and the 15 bearing on the turn-table havinga rim with which the hook hengages to prevent the pintle from rising, said bearing having also a groove, If, to initiate the engagement, the bolt g, pivoting the vane-shank to the pintle, the arm I,

projecting from the turn-table and having its 20 outer end out of line with the pintle, the link K, hook J, with its adjusting-nuts, and the operating-cords, all constructed and arranged to operate substantially as herein described.

In witness whereof I have hereunto set my 25 hand.
